Atrai River (also spelt as Atreyee) (bn|আত্রাই/আত্রেয়ী নদী|ātrāi/ātrēẏī nadī) flows in West Bengal and northern parts of Bangladesh.
In ancient times the river was called Atreyee and finds a mention in the Mahabharata, one of the two Sanskrit epics of ancient India. It is linked with Jorapani river,[2] Fuleswari river,[3] and Karatoya River. The Atrai originates in Siliguri ward no 40, near Baikanthapur forest of West Bengal and then after flowing through Dinajpur District of Bangladesh, it enters India again.[4] It passes through Kumarganj and Balurghat community development blocks in Dakshin Dinajpur district.[5] The river then renters Bangladesh. It splits into two rivers - the Gabura and the Kankra in Dinajpur district. It crosses the Barind Tract and flows into Chalan Beel.[4] The river serves as a perennial source of fishing, even though it is often the cause of flooding in many areas during monsoons.[6]
The total length of this river is approximately 240miles. The maximum depth of the river is 99feet.
